Keyboard MacBook Pro 2016, how to live with it?

Question

Keyboard

Hello!
I bought a MacBook Pro 13 2016. Everything would be very good and yes, I'm really happy with this purchase, but the keyboard made itself felt after a week. Some keys were pressed with such a sound, as if they were once flooded by the previous owner.
After googling a bunch of articles, I still dared to clean the keys myself, I managed to remove even the space bar without damage. Without sparing time, I cleaned the small specks, wiped the keys themselves, carefully removed small dust particles under the butterfly mechanism.
Some of the keys, to my happiness, began to be pressed many times better, but the next morning, a little less than half, acquired their previous state. I am ready to answer with confidence that I did everything absolutely correctly and very carefully.
Tk could not find more information, maybe someone will tell you if it is still possible to return the keyboard to its original state.

If the keyboard was filled with something sweet - the water evaporates, the sugar remains. Even if you visually washed everything with alcohol, then most likely it also got under the butterfly and it’s not realistic to wash it there without removing it.
I myself went through the red bull strait, washing the buttons 10 times - only the complete removal of the buttons with the mechanism helped, though I had only a couple of pieces where the red bull got right under the mechanism, the rest was helped by wiping the caps with alcohol and the membrane / butterflies on top. In the event that the keyboard was filled with something sweet, stains are usually visible on the inside of the buttons.
